Definitions

  • This invention relates to a device for securing an item to a substrate, in particular, to a substrate having an external panel connected thereto with a cavity formed therebetween.
  • the invention also extends to a tool for forming an opening in a substrate and external panel to enable insertion of the securing device and also to a method of securing an item using the tool and securing device.
  • Drywall lining (commonly referred to as plasterboard) is used to line the inner walls of houses and other buildings, such as offices, to provide a smooth, flat and aesthetically pleasing finish.
  • Plasterboard is usually installed by being fixed or adhered to the pre-existing substrate, which is typically a wall.
  • the most commonly used technique to secure the plasterboard is known as "dot and dab" and, as the name implies is essentially the application of dots and dabs of adhesive to the plasterboard in order to adhere it directly to the wall, or indirectly to a wooden batten connected to or forming the wall. This technique generally defines a cavity between the plasterboard and the substrate.
  • Drywall lining is cost and time effective over other existing wall finishing methods, such as wet plastering, but is subject to disadvantages.
  • the main drawback relates to the connection of items to the wall, such as shelving units or televisions.
  • items to the wall such as shelving units or televisions.
  • the plasterboard When connecting heavy items to the plasterboard it is common for the plasterboard to collapse as a result of the cavity formed between the plasterboard and the substrate. In effect, the plasterboard lacks the structural strength required to secure heavy items to the wall.
  • this does not resolve the issue, as when the securing screw (or other fixing) is tightened this tends to cause the plasterboard to be crushed as a result of the heavy item being connected, thereby damaging the plasterboard.
  • Another problem occurs as a result of the adhesive technique used to connect the plasterboard. Specifically, the adhered part of the plasterboard is far more difficult to drill through using standard drilling tools. This results in damaged and messy plasterboard, having partly drilled holes. Essentially there is a restriction of the particular locations where fixings to secure an item may be applied and that is not clear from the outside before drilling.
  • a device for securing an item to a substrate having an external panel adhered thereto with a cavity defined between the substrate and the panel comprising:
  • the enlarged head having a planar surface and being configured to be received in an opening formed in the panel, such that the planar surface is substantially co-planar with the surface of the panel when located therein,
  • the substrate will be a wall comprising a brick or stone structure and the external panel will be plasterboard adhered to the wall, though other arrangements are of course possible.
  • the securing device essentially serves to enable the connection of an item to the wall (or other substrate) rather than to the plasterboard (or other external panel) so as to utilise the structural strength of that wall or substrate.
  • the arrangement negates the need to connect devices to unstable plasterboard or other external panels and thus avoids the problems associated therewith.
  • the enlarged head of the present invention does not apply any force to the external panel and thus obviates the problems associated with structural instability.
  • the enlarged head also allows the distribution of force over the substrate which improves the connection of the device therewith.
  • the opening formed in the substrate is preferably sized to receive the elongate tube in a tight-fitting arrangement so as to provide a secure connection.
  • the elongate tube is preferably configured to expand and/or deform upon insertion of an anchoring member to maintain the securing device received in the opening formed in the substrate.
  • the inserted end of the elongate tube may be divided into two or more adjacent parts.
  • the securing device is arranged such that insertion of an anchoring member into the opposed end of the elongate tube causes radial deformation of the adjacent parts. This deformation results in the elongate tube being firmly retained within the substrate.
  • the elongate tube may include an internal screw thread configured to engage with a corresponding screw thread provided on an anchoring member. This arrangement allows a secure connection between the securing device and an inserted anchoring member.
  • the enlarged head also has a substrate engaging surface or surfaces on the opposed end, adjacent the elongate tube, for abutting against the substrate once the elongate tube has been inserted into the opening.
  • One or more surface may be planar.
  • the surface may be a single surface the same shape as the rest of the enlarged head or it may be a different shape.
  • Several separate substrate engaging surfaces may engage the substrate at various locations. Such arrangements increase the stability of the securing device and ensures that forces applied to the securing member by an item are distributed against the substrate. This serves to enhance the structural strength of the securing device.
  • the enlarged head is substantially cylindrical in shape.
  • the enlarged head may have various projections such as ribs behind the externally visible planar surface. These ribs may project radially and extend axially.
  • the securing device may further comprise means to adjust the position of the enlarged head relative to the substrate, in which the elongate tube is to be received.
  • the arrangement of the securing device may be such that it facilitates axial adjustment of the position at which the enlarged head may be held relative to the substrate. In this way fine adjustments may be made to minimise the amount of free play between the enlarged head and the wall so that the structural integrity of the securing device may be optimised.
  • the means to adjust the position of the enlarged head relative to the substrate comprises a spacer of a selected thickness positioned between the enlarged head and the substrate.
  • the spacer with the most appropriate thickness may be selected to minimise the amount of free play between the enlarged head and the wall.
  • the means may comprise a plurality of spacers of the same or different thickness. So as to enhance stability and ensure a uniform amount of force applied to the substrate by the enlarged head, it is advantageous if the spacer has a hole arranged to be in register with the opening formed in the substrate and into which the elongate tube is inserted.
  • a securing device as hereinbefore described in combination with an anchoring member arranged to be received in the hollow tube.
  • the anchoring member for insertion into the securing device may simply be a screw or may be a specially designed fixing or mount for some other component.
  • the shape of the outer profile of the anchoring member corresponds generally or substantially to the shape of the inner profile of the hollow tube.
  • the anchoring member may be arranged for insertion into the securing device simply by being urged into the securing device - with or without the use of an impact tool. Alternatively, the anchoring member may be screwed into the hole.
  • the securing device may be formed from any suitable material.
  • the securing device may be formed from nylon.
  • the material may be heavy duty nylon.
  • a drilling member configured to drill an opening in the substrate corresponding to the size and shape of the elongate tube of the securing device
  • an integral cutting member having a blade configured to cut an opening in the panel corresponding to the size and shape of the enlarged head of the securing device.
  • the tool is designed to create an opening which is suitable for the insertion of the securing device therein.
  • the opening in the substrate, formed by the tool is preferably sized to receive the elongate tube in a tight-fitting arrangement.
  • the opening in the external panel, formed by the tool is preferably sized to enable the elongate head to be received therein in a tight-fitting arrangement.
  • the close-fit arrangement allows a stable connection of the securing device with the substrate.
  • the integrated drilling member and cutting member of the tool enable the opening to be formed in the external panel and the substrate in a single action and with the strength required to allow an opening to be formed through adhered regions.
  • the drilling member is configured to drill an opening which corresponds to the shape of the elongate tube of a securing device.
  • the drilling member comprises a helical flute extending from the cutting member and having a tip at the free end.
  • the cutting member blade is preferably arranged to form a hole in the external panel. This may be achieved by using an annular blade or similar. In this case, the tool may be sprung loaded to facilitate automatic retraction of the cut-away part of the external panel.
  • the cutting member blade is spade shaped so as to cut the panel in a more gradual way and allow the waste material to fall away naturally.
  • the tool may be designed for manual operation or may be configured to connect to another tool, such as a drill.
  • the tool further comprises a standard chuck fitting to facilitate connection to a drill.
  • the opening to be formed in the substrate corresponds to the size and shape of the elongate tube of the securing device and this depends on the structural strength required. For the majority of purposes, it has been found that a length of approximately 75mm for the substrate opening is effective. In this case, the drilling member may be substantially 75mm long.
  • the size of the panel opening corresponds to the size of the enlarged head of the securing device.
  • the bigger the enlarged head the larger the surface area for connecting an item thereto.
  • a diameter of approximately 25mm for the panel opening is effective.
  • the diameter of the panel blade may be substantially 25mm.
  • This invention also extends to a method of securing an item to a substrate having an external panel adhered thereto with a cavity defined between the substrate and the panel, the method comprising the steps of:
  • Figure 1 is a side view of a securing device according to the present invention.
  • Figure 2 is a perspective view of the securing device of Figure 1 ;
  • Figure 3 is a perspective view of a tool of the present invention.
  • Figure 4 is a cross sectional view of an opening formed through a section of plasterboard and substrate
  • Figure 5 is a cross sectional view of an opening formed through a section of plasterboard, underlying adhesive and substrate.
  • Figure 6 is a cross sectional view of the securing device of Figure 1 inserted in the opening of Figure 4;
  • Figure 7 is a cross sectional view of the securing device of Figure 1 inserted in the opening of Figure 4 and having an anchoring member secured therein.
  • FIG. 4 and 5 there is shown a cross section through a wall 10 configured to receive a securing device of the present invention.
  • the wall 10 comprises a secure brick substrate 1 1 having a plasterboard panel 12 secured thereto.
  • the panel 12 is adhered to the wall by dabs of adhesive 13, defining a cavity 14 between the panel 12 and the substrate 1 1.
  • This type of wall finishing arrangement can cause problems when seeking to secure an item (not shown in Figures 4 or 5) to the wall 10.
  • the item is secured, using a fixing, to the panel 12 (either alone or in addition to being connected to the substrate 1 1 ) and this securing can cause the panel 12 to deform under the weight of the item.
  • an opening 17 has been formed through the panel 12 and into the substrate 1 1 ; these openings 17 are configured to receive a securing device of the present invention, which is described later.
  • the opening into the panel 17a is larger in diameter than the opening formed in the substrate 17b.
  • the opening into the substrate 17b is formed through a dab of adhesive 13.
  • a tool 18 for forming the openings 17 is shown in Figure 3.
  • This tool 18 is essentially a drill bit having a standard chuck fitting 19 to facilitate connection to a standard drill (not shown).
  • the tool 18 includes a drilling member 20 for drilling an opening in the substrate 1 1 and a separate but integral cutting member 21 for cutting the opening in the panel 12.
  • the integrated nature of the tool 18 ensures that the required openings 17 can be formed through the panel 12 and into the substrate 1 1 in a single straight action and with the strength required to allow an opening 17 to be formed through adhered regions 13 where necessary.
  • the substrate drilling member 20 is defined by a helical flute 22, having a sharp tip 23 to facilitate drilling into the substrate 1 1 .
  • the length of the drilling member 20 is approximately 75mm.
  • the panel cutting member 21 includes a spade-shaped blade 24 which is arranged to cut a circular opening through the external panel 12.
  • the panel cutting member 21 has a length of approximately 75mm and the spade-shape blade 24 forms an opening having a diameter of 25mm.
  • a securing device 27 to be located in the openings 17 formed in the panel 12 and substrate 1 1 of Figures 4 and 5.
  • the device 27 is formed from nylon and is used to obtain a solid and secure connection of an anchoring member 28, such as a screw, hook, or other fixing to a wall - typically to support an item 16 therefrom (e.g. a television) or to secure an object thereto (e.g. a shelf).
  • an anchoring member 28 such as a screw, hook, or other fixing to a wall - typically to support an item 16 therefrom (e.g. a television) or to secure an object thereto (e.g. a shelf).
  • the device 27 is designed to be inserted into the openings 17 purposely formed in the wall 10, as discussed above. As best seen in Figure 6, the openings 17 are sized to receive the device 27 in a tight-fitting arrangement so as to provide a secure connection.
  • the device 27 includes an elongate tube 29 configured to be received in the smaller opening 17b formed in the substrate 1 1 and having a large cylindrical head 30 at one end.
  • the cylindrical head 30 is configured to be received in the larger opening 17a formed in the panel 12.
  • a hole 33 is formed through the centre of the cylindrical head 30 and into the elongate tube 29.
  • the hole 33 defines an internal screw thread (not shown) which is configured to engage with a corresponding screw thread 34 provided on the anchoring member 28 to secure an item 16 to the wall 10.
  • the device 27 may also include a spacer 35, as shown in Figure 2, to adjust the position of the cylindrical head 30 relative to the substrate 1 1 , in which the elongate tube 29 is to be received.
  • the spacer 35 is of a selected thickness (depending on the size required) and is annular, having a hole 36 arranged to be in register with the opening formed in the substrate 17b. When the device 27 is being installed the spacer 35 is positioned over the elongate tube 29 so that it will locate in use between the cylindrical head 30 and the substrate 1 1 .
  • the cylindrical head 30 has a generally planar surface 37 at opposed ends so that, when installed in a wall 10, as shown in Figures 6 and 7, the visible part of the head 30 lies substantially co-planar with the visible surface of the panel 12.
  • the planar surface 37 on the end of the cylindrical head 30 adjacent the elongate tube 29 enables the head 30 (or spacer 35, if needed) to abut against the substrate 1 1 once the elongate tube 29 has been inserted into the opening 17b. This arrangement ensures that the weight of an item 16 anchored to the device
  • the elongate tube 29 is divided into three adjacent parts 40. As illustrated in Figure 7, the device 27 is arranged such that insertion of the anchoring member
  • an opening 17 must be formed through the external panel 12 and into the substrate 1 1 using the tool 18 described above.
  • the securing device 27 is then inserted into the opening 17 formed and the anchoring member 28 inserted in the hole 33 of the securing device 27 in a conventional manor to anchor the item 16 between the anchoring member 28 and the securing device 27.
