  • the invention to which this application relates is a fixing device and a method of manufacture thereof.
  • Attached to a rear side of the body is a pair of rotatable wings.
  • the device can fit into a borehole drilled into a plasterboard surface and, as it is inserted, the wings are positioned within the dimensions of the body. Once inserted, each of the wings may be rotated outwardly of the dimensions of the body by turning a pair of screws, associated with each wing, approximately 180 degrees, thereby securing the device to a plasterboard wall and allowing an item to be screwed thereon.
  • This provides a convenient means to affix articles to a plasterboard wall.
  • the small and fragile nature of the wings, which anchor the device means that the user is limited as to the size and, importantly, weight of the article they wish to hang while using the device.

This can leave the user unsure, and in a worst-case scenario, the wings may not have been extended sufficiently, resulting in the device becoming dislodged from the wall once the article is attached to it.

This has the effect of spreading the load borne by the device 1 across the entire surface area of the anchor member 7 and consequently reducing the pressure thereon. It is important, therefore, that the body portion 3 is provided of a depth which matches the thickness of the plasterboard wall 33 in which it is located because in instances where the depth may be less than the thickness of the wall 33, a void in the aperture of the wall 33 is created between the end of the body portion 3 and the anchor member 7.

Return movement is prevented as the proximal face of the rib or fin portions 15' is substantially flat and engages with the side wall of the ring portion 14', maintaining them in the recessed portion 13'.

  • Inserting the device 1 , 101 into the plasterboard wall 33 as shown in Figure 2b can be achieved in a number of simple steps. Once an appropriately sized hole has been made in the desired wall, the user may then, where the anchor portion 5 is formed from a separate anchor member 7 and shaft/retaining portion 25, place the anchor member 7 over the shaft 9, such that it is retained thereon by the retaining means 27. Where the anchor portion 5 is a single integral portion, this step is obviously omitted. Next, and in order to improve grip of the anchor portion 5, the user may partially insert an end of a screw/stud/nail 21 into the channel 23 of the shaft 9. A first end of the elongate anchor member 7 is then fed into the hole.
  • the anchor member 7 As the first end of the anchor member 7 and part of the retaining portion 25 are inserted into the hole, the second opposing end of the anchor member may then be urged into the hole.
  • the length of the member 7 As the length of the member 7 is provided as greater than the body portion 3 and, hence, the hole in the plasterboard 33, there may be some resistance to the insertion of the second end. Consequently, the anchor member 7 is generally constructed to have a degree of flexibility that allows it to flex slightly as it is inserted into the hole, and once inserted is sufficiently resilient to retain its shape against the rear face of the wall 33. The retention of its original shape is aided as the device becomes more securely attached to the wall 33.

  • the elongate portion 39 is provided as a flexible, resilient member.
  • the attachment member 41 is provided to be inserted at least partially into and engage with the channel 23 of the shaft 9 in the anchor member 7. The engagement may simply be via complementary screw threads provided on an exterior wall 43 of the attachment member, and an interior wall of the channel 23.
  • the attachment member also includes a head portion 45 provided for gripping by a user in use, for attachment and detachment of the applicator 37 to and from the shaft 9.

  • the shaft 9 and anchor member 7 may be inserted through the hole in the wall 33 in whatever way is convenient to the user, the shaft 9 and anchor member 7 being easily manipulated and the elongate portion 39 simply bends to accommodate the manipulation.
  • the applicator 37 is provided with a maximum diameter which is less than that of the hole 11 in the body portion 3, and so the body portion 3 of the fixing device 1 , 101 may then simply be slid down the elongate portion 39 from a second opposing end to the attachment member 41. The user may then grip a gripping portion 47 of the applicator, located at the second end, pulling the applicator 37 away from the wall 33. Consequently, this action brings the shaft 9 of the anchor portion 5 of the fixing device into the hole in the wall, with the anchor member 7 located firmly on the rear side of the wall 33. The user may then connect the body portion 3 with the shaft 9, securing the device 1 , 101 in place in the wall 33.
  • the attachment portion of the applicator 37 may then be removed from the channel 23 of the shaft 9, and a screw, nail or stud 21 , may subsequently be inserted, as required by the user.
  • the applicator 37 may then be reused for any further fixing devices 1 , 101 that are required to be fixed into the wall 33 or other walls.
  • the provision of the applicator 37 with the fixing device 1 , 101 of the present invention provides a novel and effective means by which to insert the device 1 , 101 into a wall 33 and subsequently bring the component parts of the device 1 , 101 together, with minimal fuss, saving the user time and effort.
  • the anchor member 7, when provided as a separate body, is preferably formed from a metal or metal alloy or the like, for increased strength.
  • the anchor member 7 may be formed from a plastics material.
  • the body portion 3, shaft 9 and retaining means 27 are formed from a plastics material.
  • the shaft 9 In order to receive the screw 21 in a secure fashion, the shaft 9 includes a central channel 23 located therein, as mentioned above.
  • the channel 23 generally extends through the shaft 9 from a first, front end, to a second, rear end.
  • the shaft 9 can be formed from two or more frangibly separable sections, as can be seen in Figure 3c.
  • the shaft 9 may act like a wall plug/screw anchor, but provided as far more suitable for fixings in plasterboards.
  • the body portion 3 of the device 1 , 101 may also include engagement means located on the interior wall of the hole 1 1 , provided so as to prevent relative rotation of the body portion 3 and the shaft portion 9 when the two are connected.
  • the engagement means (not shown) may be provided as at least one protrusion formed on or from at least a part of the interior wall, and preferably are provided in the form of at least one substantially flat inner wall portion located on a part of the interior wall.
  • Corresponding engagement means may also be provided on an outer wall of the shaft 9 or retaining means 25, and which are provided as one or more substantially flat outer wall portions formed thereon.
  • the present invention therefore provides a fixing device 1 , 101 having distinct advantages over the prior art. While maintaining a simple and easy to use structure, the anchor portion 5 of the device 1 , 101 may be inserted into hole in plasterboard 33 and retained in place by attaching the respective body portion 3, and any uncertainty as to whether or not it is extended to anchor the device to the plasterboard is removed.
  • the increased size and surface area of the anchor member 7, in comparison to the wings shown in EP2998592 discussed above, serves to dissipate the force/weight of the article that will hang from the device 1 , 101 , thereby reducing the pressure imposed on the plasterboard and providing a secure attachment, and permitting larger and/or heavier loads to be located on the plasterboard wall 33, without danger that the extra load could compromise the structural integrity of the plasterboard 33.
