Definitions

  • the present invention concerns fence panels, fences, methods for assembling fences and kits for assembling fences.
  • picket fences are free standing structures designed to restrict and/or prevent movement across a boundary.
  • One type of fence often used for civilian boundaries due to its aesthetic qualities is the picket fence.
  • picket fences include at least one, but often two or more, rails spanning across at least two adjacent fence posts embedded in the ground.
  • Picket fences also include a number of upright members, usually evenly-spaced, extending across and connected to the rails and oriented generally parallel to the posts.
  • the fence It is also desirable for the fence to be manufactured in a cost-effective and facile way, and be easily installed on site at a different location to where it was manufactured and/or assembled. Furthermore, it is also desirable for the fence to be manufactured from material with high weatherability and with a low chance of corrosion.
  • WO2021164923 describes a fence panel comprising a plurality of upright members and at least one rail connected to each of said upright members, wherein the at least one rail comprises an external casing defining a rail channel and comprising at least one aperture, wherein each of the upright members extends through an aperture into the rail channel, and an inner plate that extends along at least part of the length of the rail channel, wherein the inner plate is at least partly enclosed by the external casing, wherein the inner plate comprises a flat portion comprising a plurality of openings that rests against the upright members and two angled portions connected to opposite sides of the flat portion and extending away from said upright members and wherein the plurality of upright members each comprise a projection that extends into one of said openings to connect said upright member to the rail.
  • US6824123 describes a rackable fence with a rail, picket carrier, and plurality of pickets wherein the rail defines a rigid inverted U-shaped cross-section, the picket carrier includes a top span residing within and extending across the interior of the rail and the pickets are pivotally attached to the picket carrier and pivotable toward the rail.
  • US2006081828 describes a picket fence system wherein pickets are supported by a system which includes a picket support and strengthening bar and rail system.
  • US2002175321 describes a picket fence and rail mounting system.
  • the system comprises at least an upper and a lower elongate rail.
  • Each rail has a hollow interior defining a substantially l-shaped crosssection including at least a first slot and a second slot.
  • a plurality of pickets are transversely slidable through openings in an upper surface of the rails and a channel in a lower surface.
  • the pickets each have at least a first notch or indentation near a first end and a second notch or indentation near a second end.
  • An elongate retaining rod slidable within at least one rail cooperates with a notch or indentation on each picket to secure the picket to the rail.
  • spring clips, threaded fasteners or the like may cooperate with a hole in each picket to secure the picket to the rail.
  • inserts of the art typically include additional inserts or components that are made from material that are susceptible to corrosion. Additionally or alternatively, inserts of the art are typically required to be a specific shape in order to provide the sufficient stability required to hinder the rotation of an upright member.
  • a fence panel comprising: a plurality of upright members, and at least one rail connected to each of said upright members, wherein the at least one rail comprises: an external casing defining a rail channel and comprising at least one aperture, wherein each of the upright members extends through an aperture into the rail channel, a first plastic insert that extends along at least part of the length of the rail channel and is at least partly enclosed by the external casing, wherein the first plastic insert comprises a plurality of openings, a plurality of pins, wherein each pin extends through an opening in a first plastic insert to rotatably connect the upright members to the first plastic insert, and a second plastic insert that extends along at least part of the length of the rail channel and is at least partly enclosed by the external casing, wherein the second plastic insert is positioned on the side of the plurality of upright members opposite to the first plastic insert, wherein the thickness of the first and second plastic inserts increases along the axis perpendicular to the length of the
  • fence panel is to be construed in accordance with the normal use of the word to relate to a panel that can be used in combination with fence posts to create a fence.
  • the fence panel is therefore not self-supporting and is not sufficient to create a fence or other barrier alone, without some form of support.
  • the inventors have found that the fence panel of the present invention is straightforward and cheap to manufacture, with minimal and simple component parts (and fewer components than similar arrangements of the art), whilst still providing excellent structural security. Furthermore, the fence panel is rackable.
  • the angle between the upright members and the rails can be varied. In the present invention, this angle can preferably be up to 40° from the perpendicular in either direction.
  • the fence panel can be used on a sloped surface.
  • the first and second plastic inserts of the present invention create an inward force against the upright members when the inserts are positioned in the external casing, thereby restricting the ability of the upright members to freely rotate.
  • the inventors have advantageously found that that the use of a plastic material provides the necessary friction between the inserts, external casing and upright member to hinder the free rotation of the upright member. Additionally, the inventors have advantageously found that the arrangement of the present invention eliminates rattling of the upright members in the fence panel structure.
  • the first and second plastic inserts according to the present invention may have the ability to provide the necessary force against the upright member such that rotational movement is hindered.
  • the force may be greater than the force of gravity, such that the upright members are retained in a position in which they are placed, but can still be re-positioned by a user.
  • the inventors have advantageously found that the use of two separate plastic inserts according to the present invention provides the necessary friction to prevent the upright members from being loose and freely rotating. This is in contrast to arrangements in the art, for example, that utilise one insert that may surround either side of an upright member, as well as the top of the upright member in order to provide the necessary support. Therefore, the arrangement according to the present invention is more cost-effective than similar arrangements in the art.
  • the shape of the inserts can decrease the flexibility of the inserts, thereby providing improved stability to the fence panel, while also increasing the ease of positioning the inserts within the rail channel.
  • the inventors have found that the use of a plastic material for the first and second inserts, for example PVC, gives the inserts a sufficient degree of resiliency that creates the necessary friction between the plastic inserts and the upright member to hinder rotation of the upright member. While rotation of the upright member is important for the fence to be rackable, the upright members should remain in the position in which they are placed, rather than being able to rotate freely.
  • a plastic material for the first and second inserts for example PVC
  • the present invention has been found to be advantageous compared to similar arrangements in the art that include the use of non-resilient materials, for example steel, which require a specific shape in order to provide the force necessary to hinder rotation.
  • the present invention uses the inherent resilience of the material itself, thereby increasing the ease of manufacturing the component parts as a variety of shapes can be used. Additionally, the materials of the present invention are less susceptible to corrosion.
  • the first and second plastic inserts may therefore be made from a resilient material or a material having a degree of resiliency.
  • the terms "resilient” and “degree of resiliency” are to be construed as requiring that the material can be deformed under the application of a force and can subsequently return to its original shape on the removal of said force. It will be understood that any deformation in shape is not permanent.
  • a non-resilient material is to be understood as a material that either cannot be deformed or will not return to its original shape after deformation.
  • the first and second plastic inserts may be made from PVC. This is advantageous because of the inherent resilient properties of PVC and the reduced propensity for corrosion compared to other conventional inserts or plates used in the art, for example, those made from steel.

  • the first and/or the second plastic inserts may have a hardness of lower than 80 HA, preferably lower than 60HA.
  • the first and/or the second plastic inserts may have a Break Extend Rate of over 250%, preferably over 300%.
  • a low hardness and/or a high tensile strength allows the plastic inserts to be more deformable and resilient. This means that the tolerances can be improved, along with the friction exerted by the inserts on the upright members.
  • the first and second plastic inserts may be the same length.
  • the first and second plastic inserts may be different lengths.
  • the second plastic insert may be longer than the first plastic insert.
  • the first and/or second plastic insert may extend the entire length of the rail channel, preferably more than 80% of the length of the rail channel and more preferably more than 90% of the length of the rail channel.
  • first and second plastic inserts of the invention are cheaper to manufacture compared to similar arrangements in the art, as no separate shaping process is required after the inserts have been created. Further, the inclusion of one plastic insert that is shorter than the other has been found to improve structural integrity of the fence panel, as shorter plastic inserts are less flexible in nature. Furthermore, the inventors have found that the use of first and second plastic inserts according to the present invention yields fencing that is easier to assemble and is simpler compared to fences in the art.
  • the first and second plastic inserts may have one thick portion which tapers down to a thinner portion, thereby forming a wedge-like shape. The change in thickness is along the height of the inserts, i.e. the dimension parallel to the length of the upright members.
  • the first and/or second plastic inserts may have thinner portions at each end thereof, with a thicker portion in between.
  • the thicker portion is preferably closer to one end than the other. Additionally or alternatively, there may be a bend or curve at one end of the first and/or second wedges.
  • This shape for the first and second plastic inserts is advantageous because it can be easily inserted into the arrangement of the present invention and therefore construction is simple.
  • the thicker portion of the plastic inserts can apply a pressure against the upright member, creating the necessary friction to hinder rotation.
  • the thicknesses of the first and second plastic insert may be the same.
  • the thicknesses of the first and second plastic insert may be different.
  • the thickest portions of the first and second plastic inserts may be in contact with both the upright member and the external casing. The thickest portions of the first and second plastic inserts may therefore provide the necessary force to hinder the rotation of the upright members.
  • the thickest portions of the first and second plastic inserts are preferably opposite one another, at the same height along the upright member.
  • the thickest portions of the first and second plastic inserts may be positioned away from the upper side of the external casing. This shape has been found to result in easy insertion of the first and second plastic inserts, while still providing the necessary force to hinder the rotation of the upright members.
  • the thickest portion of the first and second plastic inserts may be positioned towards the upper side of the external casing. This shape has been found to provide the greatest amount of friction and contact between the insert and upright member, thereby improving the stability of the upright members.
  • upper and lower herein are to be construed with reference to the surface on which the fence panel is to be placed. Thus, the lower side is that closest to the surface, while the upper side is that furthest from the surface.
  • the external casing includes any protrusions that also may be present in the external casing.
  • the external casing may comprise at least one first aperture and at least one second aperture opposite the at least one first aperture, wherein each of the upright members extends through a first and second aperture and thereby extends through the rail channel. This allows the rail to be positioned at any point along the length of each upright member (for example along the top, middle or bottom of the upright members). Thus, multiple rails can be positioned at different heights of the fence panel.
  • the external casing comprises a plurality of apertures such that each upright member extends through a different aperture.
  • Said plurality of apertures may be a plurality of first apertures.
  • the plurality of apertures ensures that each upright member is held in place and limits the extent to which the upright members have rotational freedom. The extent of the rotational freedom is at least partially dictated by the size of said apertures.
  • the first apertures are preferably on an upper side of the external casing.
  • the external casing may comprise one aperture extending along at least part of the length thereof, such that all of the upright members extend through the same aperture.
  • This aperture may be the second aperture.
  • This aperture may extend along the entire length of the external casing. This aperture may be on a lower side of the external casing.
  • the combination of the plurality of first apertures and the single second aperture increases the ease with which the upright members are positioned relative to the rail, as each upright member only needs to be aligned with a first aperture. Such an arrangement is also cheaper and easier to assemble, whilst maintaining the stability of the upright members, which is provided by the first apertures.
  • the cross-section of an aperture may be greater than the cross-section of the upright member extending therethrough.
  • cross-section is used in this context to refer to the cross-section parallel to the side of the external casing comprising the aperture. This may be the case for all apertures in the external casing and is particularly important for the plurality of first apertures, if present.
  • the cross-section of the aperture may be greater than the cross-section of the upright member in one dimension, or in all dimensions.
  • the external casing may have a rectangular cross-section.
  • the external casing may comprise two sides parallel to the upright members and two sides perpendicular to the upright members. However, at least one of the sides perpendicular to the upright member includes an aperture.

The dimensions of the external casing may be such that the sides of the external casing parallel to the upright members are longer than the side(s) of the external casing perpendicular to the upright members.
  • the external casing may comprise a lip adjacent to an aperture and extending into the rail channel.
  • the lip may be connected to the external casing at the boundary between said external casing and the aperture.

  • the lip may comprise a section angled towards the inside of the external casing, away from the lower side. The lip may extend partly over the aperture.
  • the lip may provide a channel in which an end of the first plastic insert can rest. Therefore, the height of the first plastic insert may extend the majority of the height of the rail channel, for example, from the upper side of the external casing to the lip of the external casing.
  • the lip may also ensure that the size of the cross-section of the aperture in the dimension perpendicular to the length of the rail channel is similar to the size of the cross-section of the upright members in the same dimension. This prevents movement of the upright members in this dimension, and thus improves stability of said upright members.
  • the lip may be on the side of the second plastic insert and these features apply equally in this case.
  • the lip may be angled at about 0° to about 80°, preferably about 20° to about 80°, more preferably about 20° to about 70°, most preferably about 30° to about 70°, relative to the side of the external casing comprising the aperture.
  • the inventors of the present invention have found that such an angle provides optimal positioning of the plastic insert inside the external casing to maximise stability and security, especially compared to arrangements of the art which are absent the lip, or have an angle greater than about 80°.
  • a lip having this angle makes it more difficult to remove the top rail from the arrangement.
  • the inventors of the present invention have also found that the external casing comprising a lip having such an angle is cheaper and easier to manufacture compared to arrangements of the art which have an angle greater than about 80°.
  • the first plastic insert may contact the external casing between a side of the external casing extending parallel to the upright member and the lip. Additionally or alternatively, the first plastic insert may contact the external casing between the upright member and the external casing. This provides extra stability and security to the first plastic insert inside the external casing, particularly in view of the forces applied to the first plastic insert by the pins as the upright members are rotated.
  • a thinner end of the first plastic insert may be positioned between the lip and a side of the external casing extending parallel to the upright member.

  • the length of the protrusion may be complementary to the thickness of the plastic insert at the height of the protrusion in the external casing. For example, the thinner the section of the plastic insert that is in contact with the protrusion, the longer the corresponding protrusion may be.
  • An upper protrusion may act to hold the second plastic insert against the upright member, thereby applying the necessary forces to hold the upright member in place and hinder rotation of the upright member. This can also reduce the friction created when the second plastic insert is pushed along the rail channel, as it is only in contact with the protrusion rather than the entire surface of the external casing.
  • the protrusions in contact with the surface of the second plastic insert, that act to hold it against the upright member must have a length such that the plastic insert can slide past them, between the external casing and the upright member.
