This invention relates to a hanger device for mounting a frame or other hanging element on a wall so as to be suspended along the wall from the hanger.
Typically such suspended frames include a wire attached at ends of the wire at or adjacent the sides of the frame with the wire extending loosely across the rear of the frame. The wire is then hung over a nail or other fastener penetrating into the wall. Sometimes where the object is heavy, the user applies two wall fasteners at spaced positions across the rear. In all cases, locating the frame in a required position and preventing the frame from tilting side to side is difficult and remains an issue of concern in almost all homes and workplaces where such frames are hung.
The term picture frame as used herein is defined to include other components such as mirrors, photograph frames, art frames and any other structure or object which uses the conventional wire mounting system strung across the rear of the frame.

In the drawings like characters of reference indicate corresponding parts in the different figures.
As shown in the above U.S. Pat. No. 9,107,520,
The apparatus is defined by an flexible spring member 15 shaped by suitable forming techniques from a spring steel material or molded plastics material to define a center mounting plate or portion 16 and a spring strap 17. The mounting portion 16 has a flat rear surface 161 arranged to lie flat on the wall 13 and to be attached thereto by a fastener 162. The mounting portion 16 has a width sufficient merely to provide an effective mounting and has a horizontal bottom edge 163 and a horizontal top edge 164 attached to the strap 17.
The spring strap includes a wall 171 at right angles to the surface 161 of the portion 16 and therefore to the wall 13 so as to stand outwardly from the wall 13. The spring strap has a pair of arms 172 and 173 each extending outwardly from the mounting portion 16 along the wall to a respective side of the mounting portion 16.
The arms 172 and 173 of the spring strap thus have a flat upper surface 174 defined by the wall 171 and are arranged to receive the wire 12 of the frame resting on the surface 174 with the wire extending along the arms 172 and 173 so that the wire is carried on the arms to the ends 175 and 176 of the arms.
The arms 172 and 173 have at spaced positions along the length thereof upstanding tabs 18 and 19 on a rear face of the surface 174 for resting against the wall. The strap 17 also includes a front tab 20 centrally of the apparatus at the mounting portion 16 at the front edge of the surface 174 for resting against the rear of the object.
Thus the wire 12 is confined to extend along the strap 17 to the ends 175 and 176 and depends from ends of the arms to the sides of the frame 11.
As shown in the Figures, the arms 172 and 173 of the spring strap are slightly arched in an initial undistorted or rest position as supplied. However the arms are flexible under the weight of the frame 11 so bend downwardly as shown at arrows D in
The spring strap has a plurality of wire engaging elements or tabs 18, 19 and 20 thereon to hold the wire 12 so that the wire is confined between the tabs and extends along the strap as the arms bend downwardly. The tabs 18, 19, 20 and 23 are formed by molding in the plastics version or, in a spring steel version, by stamping an edge portion on the arms and by bending this portion upwardly at right angles to the strap.
The wire engaging elements and the arms allow frictional sliding longitudinal movement of the wire 12 along the arms 172 and 173 and therefore allow movement of the frame side to side relative to the mounting plate in an initial adjustment operation.
In an alternative arrangement, instead of placing the hanger first on the wall and hanging the wire over the arms, the arms and hanger can first be attached to the wire and located in the required position, following which the mounting plate is hung over a suitable fastener such as a screw or nail in the wall. Thus the single hole of the plate 16 may be replaced by key-hole slot or a hook arrangement.
There is thus provided an apparatus 10 for hanging an object 11 by a wire 12 of the object on a wall 13, where the wire 12 extends across a rear of the object and is connected to the object at or adjacent the sides of the object.
As explained above, the apparatus includes the flexible spring member 15 shaped to define the center mounting portion 16 having a mounting surface 161 arranged to lie flat on the wall 13 and to be attached thereto by one or more fasteners 162. The spring strap 17 carried by the center mounting portion 16 provides the surface 174 standing generally outwardly relative to the surface 161 and therefore to the wall 13. The spring strap 17 has a pair of arms 172 and 173 each extending outwardly from the mounting portion 16 along the wall to a respective side of the mounting portion.
The arms of the spring strap 17 are arranged to receive the wire 12 of the object extending along the arms so that the wire 12 is carried on the arms and depends from ends of the arms to the sides of the object. The arms 172 and 173 of the spring strap 17 are flexible under the weight of the frame 11 so that they flex downwardly from the mounting portion 16 to the ends 175, 176. The spring strap 17 has the plurality of wire engaging elements in the form of the tabs 18, 19 and 20 thereon to hold the wire so that the wire extends along the strap as the arms flex downwardly without the wire falling to the front or rear so that the wire follows the contour of the strap as it flexes. At each of the ends 175, 176 is provided a V-shaped notch member 21 extending transverse to the arm 17 and standing upwardly from the upper flat surface of the arm and forming a groove 211 through which the wire 12 passes and arranged to apply frictional contact to the side of the wire to better hold the wire and to reduce movement of the wire side to side across arms the to keep the wire located at the ends 175 and 176. Thus the weight of the object or frame even if significantly unbalanced does not cause the wire to slide across the arm and tilt to one side and instead the unbalance of the weight tends to be taken up in the arms and hold the object level even if unbalanced.
However the groove 211 and the wire tabs 18, 19, 20 and the upper surface of the arms allow longitudinal adjustment movement of the wire along the arms and therefore allow adjustment movement of the object side to side relative to the mounting plate and the arms. Thus the flexing of the arms acts to hold the object when adjusted level to reduce side to side tilting of the object. The groove 211 can be sharper than that shown with a narrower angle to provide a better frictional contact with the sides of the wire.
The rear half 212 of the notch member 21 includes a rearwardly inclined blade portion 22 extending longitudinally of the arm over a short distance at the end of the arm so as to engage the wall surface at the rear of the surface 174. Thus when the hanger is initially applied, it sits in contact with the wall with the blade having a top edge at the wall surface. In this way the wire of the frame slides down the wall as the frame is applied and is prevented by the blade 22 from engaging behind the surface 174 so that it lies onto the surface 174 in the required position. When the frame is properly engaged and released by the user, the frame tends to lean forward so that its top edge is forward of the wall and the wire is pulled forwardly. However the wire remains on the surface 174 retained by the guide tab 20 and the blades 22.
The center mounting portion 16 includes three holes for use in fastening the rear surface 161 to the wall. A main central opening 165 for receiving the fastener 162 includes a sleeve 166 extending generally outwardly from the surface 161 for guiding the fastener 162 into engagement with the wall so that a head of the fastener abuts against the end 167 of the sleeve to hold the surface 161 tight against the wall. The sleeve 166 is inclined upwardly and outwardly from the surface. The center mounting portion 16 includes additional fastening holes 168, 169 adjacent to and on either side of the sleeve 166 for receiving additional fasteners if required for increased stability or to accommodate increased weight. The size of the plate can be larger to provide sufficient space to receive the three fasteners through the holes 162, 168 and 169. Further the rear surface 161 of the center mounting portion 16 includes pointed projecting elements 16A, 16B extending outwardly or rearwardly from the surface 161 for engaging into the wall again for increased stability. In cases where the object does not overload the flexibility of the arms, the arms are used alone to support the wire. However in some cases additional strength is required in which case an additional flexible stiffening rod 25 is provided which extends along the strap underneath the arms with ends 26 and 27 at the ends of the arms. In order to hold this stiffening rod in place when required, the underside of the arms as best shown in
Turning now to
The mounting plate is formed by the generally flat centre section with side edges 120 and 121 and includes the side stiffening flanges 122 and 123 on either side of a centreline 125 passing through the centre of the mounting plate 116 and extending downwardly to a bottom apex 124 of the bottom of the generally rectangular mounting plate.
In order to properly orient the centreline 125 in and accurately vertical orientation, there is provided a plumb member 126 which is arranged to be mounted on the post 117 so as to hang from the post with a bottom apex 1 to 7 of the plumb member pointing downwardly along and accurately vertical line defined by the plumb member. The bottom apex 124 of the mounting plate includes a marker 128 with an upwardly pointing apex arranged to accurately align with the bottom apex 127 of the plumb member when the centreline 125 is accurately vertical as defined by the bottom apex of the plumb member.
The post 117 which also acts as a guide for the first fastener has a central hole through which the fastener can be inserted. The post 117 also includes a cylindrical support surface 129 surrounding the post onto which a collar 130 of the plumb member 126 can be mounted for free rotation of the collar around the post to accurately take up the vertical position.
The support 117 is located at a position generally central of the mounting plate so that it is located below the spring arch and above the bottom marker 128. This leaves room for a length of the plumb member which is sufficient to accurately define the vertical line. Thus the support is located on the front face of the centre mounting plate facing away from the wall surface onto which the device is attached. The post 117 bus projects forwardly from the mounting plate and is carried on a support portion 133 so as to hold the post and the plumb member thereon space forwardly from the mounting plate to avoid frictional engagement with the mounting plate. In this way the plumb member is freely suspended on density rotates around the post.
