Definitions

  • the invention relates to a wall hanger for hanging an object, such as for instance a picture, mirror or the like, on a wall.
  • wall hangers are often not suitable and/or reliable when the wall is a hollow wall, in particular when the hollow wall comprises a relatively weak drywall or wallboard panel, such as a gypsum panel, mounted in front of another wall element, such as masonry wall. In such cases, it may be hard to properly install the wall hanger, especially when there is no convenient wood stud or the like behind the wallboard panel at the location where the wall hanger is desired.
  • drywall anchors and wall hangers have been proposed, such as toggle bolts, plastic toggle anchors, and so-called molly bolts.
  • mounting such a drywall anchor or wall hanger usually requires suitable tools and/or skills, which can make the installation difficult, time-consuming, and/or error prone.
  • Another disadvantage of known drywall anchors and wall hangers lies in that they usually require a lot of space between the wallboard panel and the wall element finished by said wallboard panel in order to allow an anchoring part of said drywall anchor or wall hanger to be properly placed into the wall.
  • the present disclosure aims at providing a wall hanger that on the one hand can be mounted relatively well to a hollow wall having a relatively narrow space between its wallboard panel and a second wall element covered by said wallboard panel, while it can on the other hand be installed in a relatively simple, relatively swift, and/or relatively error insensitive manner, preferably without requiring special tools and/or skills.
  • the invention provides for a wall hanger for hanging an object on a wall, comprising an elongate anchor part for anchoring the wall hanger to the wall, said anchor part including a substantially C-shaped hook portion having a pointed distal end for anchoring at the rear side of a wallboard panel of the wall, wherein a proximal end of the hook portion merges into a second portion of the anchor part, said second portion interconnecting the substantially C-shaped hook portion with a connector part for holding the object to be hung to the wall hanger, wherein said anchor part has a height not being greater than 1.5 times its depth.
  • the pointed distal end of said substantially C-shaped hook portion of the anchor part will curl back to the wallboard, i.e. to the rear side of said wallboard due to the curved shape of the substantially C-shaped hook portion, as a result of which the pointed distal end, which is for anchoring the wall hanger at the rear side of the wallboard, can be brought into engagement with said rear side in an elegant manner.
  • the wall hanger can be turned by moving the connector part down, thereby moving the pointed distal end of the anchor part upward behind the wallboard panel.
  • the pointed end curls back to the wallboard and can cut into the rear side of the wallboard panel.
  • the anchor part curves back relatively strongly when the height of the anchor part is relatively small with respect to the depth of the anchor part, especially when said height does not exceed 1.5 times the anchor part's depth, the anchor part can be used relatively well to mount the wall hanger on a hollow wall having a relatively narrow hollow space.
  • the anchor part which thus has a relatively small height in comparison to its depth, can
  • the pointed end of the anchor part can accidently hook behind a protrusion, e.g. a protruding mortar joint, or in a cavity of such masonry wall.
  • a protrusion e.g. a protruding mortar joint
  • the relatively low height of the anchor part in combination with the shape of the anchor part, which comprises a curved C-shape, in particular a substantially circular arc-shape, and a second portion extending away from the proximal end of the substantially C-shaped portion, can facilitate that the centre of rotation about which the wall hanger is rotated upon installation may, at least during a first part of said installation, lie relatively far forward, i.e. relatively far in front of a wall element, such as a masonry wall, extending behind the wallboard panel.
  • the anchor part's second portion especially the proximal end of said second portion, and/or the connector part connected to said second portion, especially when being substantially rigid, may counteract that the pointed distal end of the substantially C-shaped hook portion will stuck relatively far behind the wallboard panel before it will be curled up to such extent that it is directed to the rear side of the wallboard panel instead of being directed away from said rear side.
  • the anchor part's second portion especially the proximal end of said second portion, and/or the connector part connected to said second portion, especially when being substantially rigid, may abut the front side of the wallboard panel, and may then force a user to rotate the substantially C-shaped hook portion shortly after its pointed distal end reaches the rear end of the through hole, thereby forcing a user to curl back the pointed distal end relatively swiftly, i.e. before it reaches relatively deep behind the wallboard panel. It can thus be facilitated that the anchor part is only moved relatively deep into the hollow space behind the wallboard panel after the pointed end is already directed towards the rear side of the wallboard panel instead of still being directed towards the wall element, such as a masonry wall, extending behind the wallboard panel.
  • a wall defining a relatively narrow space behind its wallboard panel can be provided in a relatively simple, relatively swift, and/or relatively error insensitive manner with a connector, formed by the connector part of the wall hanger, for hanging an object, such as a picture, onto said wall.
  • the through hole in the wallboard panel may have a height which is relatively large compared to the corresponding thickness of the anchor part.
  • the height of the through hole may be at least 40%, preferably at least 50% or at least 60% larger than said anchor part's thickness.
  • the height of the through hole may be at least 1.5 times, for example at least 2, 2.5 or at least 3 times as large as the anchor part's thickness formed by said diameter.
  • the substantially C-shaped hook portion of the anchor part substantially as a circular arc, in particular such that the circular arc subtends an angle at the centre of the imaginary circle of the circular arc that is at least 135°, preferably at least 150° or at least 165°, such as about 180°, it can be facilitated that the pointed distal end of the
  • substantially C-shaped hook portion curves backs relatively strong, and, during installation of the wall hanger, moves relatively swiftly away from any element, such as a masonry wall, located behind the wallboard panel, thereby counteracting that the anchor part gets stuck.
  • the anchor part By making the elongate anchor part relatively rigid, it may be counteracted that the anchor part unintentionally deforms. For example, it may be counteracted that the anchor part deforms unintentionally due to the shape of the through hole when it is being passed through said through hole. It may thus be counteracted that the pointed distal end does not curl back in time, but sticks towards a masonry wall. For instance therefore, making at least the elongate part, and preferably substantially the complete wall hanger, relatively rigid, may further counteract that the hook portion accidentally gets stuck behind the masonry wall. Additionally or
  • the relatively high rigidity may facilitate in that in case the pointed distal end of the substantially C-shaped hook portions would nevertheless hook behind a masonry joint, which is relatively brittle, the hook portions could be pushed through such masonry joint protruding from the masonry wall located behind the wallboard panel, without deforming the substantially C-shaped hook portion, such that the pointed tip of said substantially C-shaped hook portion will still curl back to the wallboard and can then anchor into the rear side thereof.
  • the elongate anchor part, and preferably substantially the complete wall hanger is rigid to such extent, that once the wall hanger is mounted in a gypsum wallboard, it will substantially not deform when a 40 kg load is applied. More preferably, it will be rigid enough to prevent that it will substantially deform when a load of at least 60 kg, at least 100 kg, or even 150 kg, is applied.
  • the anchor part can be formed such that, at a location near the pointed distal end of the anchor part's substantially C-shaped hook portion, the tangent line to the curve of the central axis of said substantially C-shaped hook portion is, in the installed position of the wall hanger, at a predefined angle with the wallboard panel of the wall, wherein said predefined angle is at least 45°.
  • the pointed distal end of the substantially C-shaped hook portion curves backs relatively strong, and, during installation of the wall hanger, moves relatively swiftly away from the wall element located behind the wallboard panel, thereby counteracting that the anchor part gets stuck.
  • the anchor part By forming the anchor part such that, at a location near the pointed distal end of the anchor part's substantially C-shaped hook portion, the tangent line to the curve of the central axis of said substantially
  • C-shaped hook portion is at a predefined angle with the central axis of the anchor part's second section, which second section may preferably extend substantially in a linear direction, and wherein said predefined angle is at most 45°, it can be facilitated in a relatively elegant manner that the pointed distal end curves backs relatively strong, and, during installation of the wall hanger, moves relatively swiftly away from the wall element located behind the wallboard panel, thereby counteracting that the anchor part gets stuck.
  • the total length of the elongate anchor part measured from the proximal end of its second portion up to its pointed distal end, is at most 3 times the length of the second portion of said elongate anchor part, preferably at most 2.5 times.
  • said total length of the elongate anchor part may be such that it is not longer than 6 cm, preferably at most 5 cm, such as about 4 cm or about 3.5 cm.
  • the height of the anchor part can be at most 30 mm, preferably at most 28 mm, more preferably at most 25 mm, such as about 20 mm, and/or the depth of the anchor part is at most 25 mm, preferably at most 23 mm, more preferably at most 20 mm, such as between 15 mm and 20 mm.
  • the wall hanger By integrally making at least the anchor part, and preferably the entire wall hanger, from wire material, in particular metal wire, more in particular steel wire, the wall hanger can be of a relatively simple and/or cost efficient design.
  • the diameter of the wire material may be between 1.7 mm and 3.5 mm, more preferably between 2 mm and 3 mm, in particular about 2.5 mm.
  • the connector part has a mass being larger than the mass of the substantially C-shaped hook portion, as a result of which it can be facilitated that when the anchor part's second portion extends through the through hole, and the wall hanger has been installed, the wall hanger may stay in its intended upright position and it can thus be counteracted that it unintentionally turns about the central axis of the anchor part's second portion. Thanks to the relatively heavy connector part, it might even be facilitated that the wall hanger, when the pointed distal end has not yet been firmly anchored into the wallboard panel's rear side, might, due to gravity, turn towards an upright position in which the substantially
  • the C-shaped hook portion extends upwards from said second portion and said connector parts hangs downwards from said second portion.

  • said distal end 112 can be bevelled such that a distal end 117 of the bevelled edge 118 forming the tip 117 of the pointed distal end 112 is located more inward with respect to the curvature of the substantially C-shaped hook portion 111 than a proximal end 119 of the bevelled edge 118.
  • the point 117 of the pointed distal end 112 can be located at the inward side of the central axis Alll of said substantially C-shaped hook portion 111, whereas the proximal end 119 of the bevelled edge 118 can be located at the outward side of said central axis Alll.
  • the bevelled edge 118 and the outer edge El 11 of the substantially C-shaped hook portion 111 can substantially enclose an obtuse angle ⁇ , preferably an angle ⁇ being at least 100°, more preferably at least 110°, such as at least 120°.
  • the corner connecting the outer edge El 11 of the hook portion 111 and the bevelled edge 118 can be relatively blunt, for instance by rounding it off, thereby counteracting that said corner itself may get stuck unintentionally. It is believed that the use of the wall hanger 1 will be apparent to a person skilled in the art.
  • the wall hanger 1 can be installed by pushing its pointed distal end 112 through the wallboard panel 21, and subsequently, or at least partly simultaneously, turning the wall hanger, as is shown in Fig. 1 by means of arrow 3.
  • an object such as a picture, a mirror, or the like, may be connected to the connector part 12 to be suspended therefrom.
  • a load applied to the connector part 12 will be directed in a vertical direction.
  • dimensions of the through hole 22 in the wallboard panel 21 can have no or only relatively very limited impact on the extent to which the wall hanger 1 is anchored into the wallboard panel 21.

Abstract

La présente invention concerne un support mural pour suspendre un objet sur un mur. Le support mural, qui peut de préférence être formé à partir d'une seule pièce de fil d'acier étiré, comprend une partie d'ancrage allongée pour ancrer le support mural au mur. La partie d'ancrage comprend une partie de crochet sensiblement en forme de C ayant une extrémité distale pointue pour un ancrage au niveau du côté arrière d'un panneau mural du mur. Une extrémité proximale de la partie crochet fusionne dans une seconde partie de la partie d'ancrage. Le support mural comprend en outre une partie de connecteur pour maintenir l'objet à suspendre au support mural. La seconde partie de la partie d'ancrage interconnecte la partie de crochet sensiblement en forme de C avec ladite partie de connecteur. Au moins la partie d'ancrage du support mural, et de préférence l'ensemble du support mural, est sensiblement rigide. De plus, la partie d'ancrage a une hauteur qui n'est pas supérieure à 1,5 fois sa profondeur.
