Patent Application
20220211194
The application relates generally to devices operable to hang an object on a wall, more specifically but not by way of limitation an apparatus configured to suspend an open back canvas or art board either with or without a frame, wherein the apparatus includes a wall member and a frame member.
Homeowners regularly decorate the interior of the rooms of their homes. Paintings and pictures are typically framed works of art with the former many times being applied to a canvas or similar item having an open back design. Various types of hanging devices are known, including French cleats.
U.S. Pat. No. 9,521,915 describes on variation of a French cleat in the form of an apparatus operable to provide hanging of an object (e.g., an open back canvas) on a vertical wall. The apparatus includes a wall member and a frame member. The wall member includes a lower portion and an upper portion. The upper portion is configured to angularly extend away from a wall subsequent to mounting. The upper portion of the wall member includes a first leg member and a second leg member with an intermediate channel. The frame member includes an upper surface operable to support an object thereon. A lip is formed along the rear perimeter edge of the upper surface. The frame member includes an upper portion having an angular perimeter edge. Contiguously formed with the upper portion is an arm that is configured to extend downward therefrom. The arm is inserted into the channel.
Existing French cleats put notable loads on the wall bracket portion that attempt to pull it from the mounting surface if the object is warped away from the wall at center or if, in the case of a canvas covered frame, the canvas is folded in multiple layers at the corners. Moving the bottom of a mounted object away from the wall applies similar forces that can loosen or dislodge the wall bracket if the fasteners cannot withstand substantial loads.
Accordingly, there is a need for a French cleat type hanging apparatus that addresses one or more of the foregoing limitations.
In one aspect, an apparatus for supporting an object on a wall includes a wall member including a rear side defining a wall mount plane to be held against a wall surface and a recess defined at least in part by a front wall portion that extends upwardly and forwardly from a support ledge, wherein the recess includes an open top section. A frame member includes a frame mount section for engaging a frame, and an arm extending downward from the frame mount section for positioning down into the recess of the wall member such that the frame member will be supported by the wall member. The front wall portion and the arm are configured such that an interaction of the arm and a rear surface of the front wall portion during a downward movement of the arm into the recess while the frame mount section is spaced away from the wall surface will cause at least one of the front wall portion or the arm to flex in order to enable a bottom end of the arm to continue downward toward a seated position.
In another aspect, an apparatus for supporting an object on a wall includes a wall member including a rear side defining a wall mount plane to be held against a wall surface and a recess defined at least in part by a front wall portion that extends upwardly and forwardly, wherein the recess includes an open top section. A frame member includes a frame mount section for engaging a frame, and an arm extending downward from the frame mount section for positioning down into the recess of the wall member such that the frame member will be supported by the wall member. The front wall portion and the arm are configured such that an interaction of the arm and a rear surface of the front wall portion during a downward movement of the arm into the recess while the frame mount section is spaced away from the wall surface will cause at least one of the front wall portion or the arm to move in order to enable a bottom end of the arm to continue downward toward a stop position.
In a further aspect, an apparatus for supporting an object on a wall includes a wall member including a rear side defining a wall mount plane to be held against a wall surface and a recess defined at least in part by a front wall portion that extends upwardly and forwardly, wherein the recess includes an open top section. A frame member includes a frame mount section for engaging a frame, and an arm extending downward from the frame mount section for positioning down into the recess of the wall member such that the frame member will be supported by the wall member. The recess includes end plates that prevent the arm from sliding laterally out of the recess.
The details of one or more embodiments are set forth in the accompanying drawings and the description below. Other features, objects, and advantages will be apparent from the description and drawings, and from the claims.
Referring to
The opposite ends 18, 20 of the wall member include end plates 40, 42 that have rear edges 44, 46 that are co-planar with each other along most of a height H1 of the wall member 12, and also co-planar with the rear edge 48 of a bottom ledge 50 extending across the width W1 of the wall member 12 and a rear edge 52 of an upper ledge 54 extending across the width W1. The collective rear edges 44, 46, 48 and 52 therefore define or lie in a wall mount plane 56 of the wall member 12.
At the front side of the wall member 12, a lower front wall portion 60 runs substantially vertically (e.g., parallel to the wall mount plane 56), a middle or intermediate front wall portion 62 extends at an angle 01 (relative to wall portion 60) forward and upward from the lower front wall portion 60 to the upper ledge 54, and an upper front wall portion 64 extends at an angle θ2 (relative to wall portion 60) forward and upward from the upper ledge 54, where angle θ2 is greater than angle θ1. By way of example, angle θ1 may be between 7 and 13 degrees, and angle θ2 may be between 18 and 24 degrees, though other variations are possible. The surfaces may also be curved in some embodiments. Notably, each buttress projection 26 includes a portion on a front surface of the upper front wall portion 64 and a portion on a front surface of the intermediate front wall portion 62.
A rear recess 70 at the back side of the wall member is bounded by the front wall portions 60 and 62, the ledges 50 and 54 and the lower sections of the end plates 40 and 42. Support struts 74 are also provided within the rear recess 70 and run between the ledges 50 and 54. A rear recess 72 at the back side of the wall member is bounded by the front wall portion 64, the upper ledge 54 and the upper sections of the end plates 40 and 42. Unlike recess 70, recess 72 is not bounded at the top, enabling the recess 72 to receive part of the frame member 80. In this regard, a lip 76 extends upwardly from the top surface of the upper ledge 54 and is spaced from the front wall portion 64 to form a lower receiving slot 78 between the two. Thus, the lip 76 and front wall portion 64 may be considered spaced apart upwardly extending legs with an intermediate channel therebetween.
The frame member 80 includes a ledge 82 with a planar upper surface 84 and an upwardly extending lip 86 having a forward facing surface 88. The surfaces 84 and 86 of the ledge 82 and lip 86 form a right angle that is well suited to receiving an object, such as a picture or art frame (e.g., a frame of an open back canvas), for mounting to the object. Thus, the ledge 82 and lip 86 together form a frame mount section of the wall member. The frame member 80 includes fastener apertures 90 for such purpose, with the apertures 90 oriented at an angle with respect to the surface 84, per aperture axis 92. The apertures 90 extend through the ledge 82 and through aperture bosses 94 located at, and projecting down from, the underside of the ledge 82. As best seen in
In one implementation, both the wall member 12 and the frame member 80 are formed of PVC or other plastics material (e.g., by molding all portions as a monolithic unit) with geometry and material properties that support deflection of the flexible member to provide elastic lateral movement of the end of the arm in relation to the upward wall of the wall bracket by at least 1/16″, individually or in combination. Alternative designs employing springs to facilitate elastic flexure of rigid members are also possible, as well as hinged connections without springs. This is different than the typical French cleats of the prior art, which are commonly made of metal (e.g., extruded aluminum) or wood.
In this regard, reference is made to the cross-sections of
The flexing feature of the described mounting apparatus makes the apparatus better suited to mounting of framed objects in which the frame is either warped away from the wall at center or has bunched corner regions which tend to hold the frame member away from the wall, thereby reducing the likelihood that the forces of the interacting frame member 80 and wall member 12 will tend to pull the wall member away from the wall. When the frame member 80 is subsequently removed from engagement with the wall member 12, the arm 110 will, as a result of material/shape memory, revert back to its normal position, and thus is suited for use multiple times. Notably, the end plates 40 and 42 bound the sides of the recess 72, to prevent the arm 110 from being able to slide laterally out of the recess.
As noted above, the flexing of the arm occurs in situations where the frame section of the frame member 80 are not able to contact the front surface of the wall 200 (e.g., when the rear side of the lip 86 is held away from the wall surface for some reason, which typically is due to the configuration of the frame or something attached to the frame, such as canvas. In situations in which the rear side of the lip 86 is able to contact the front surface of the wall 200, the arm 100 does not need to flex in order for the bottom end of the arm 110 to reach and be supported by the ledge 54, as reflected in
It is to be clearly understood that the above description is intended by way of illustration and example only, is not intended to be taken by way of limitation, and that other changes and modifications are possible. For example, while the arm 110 in the illustrated embodiment is shown and described as curved along a majority of its height, the arm could include planar sections or could be majority planar. It is also possible to configure the components such that the upwardly extending front wall portion 64 of the wall member 82 flexes, rather than, or in combination with, the arm 110. It is further possible to configure the components such that some or all flexing is achieved by other portions of either or both the wall member 12 and/or the frame member 80. Moreover, although the fully seated position of the arm in the illustrated embodiment is with the bottom end of the arm atop the ledge 54, in other variations the fully seated position or stop position could place the bottom end of the arm 110 above the ledge 54, such as seating against some other structure of the bracket 12 (e.g., structure at or protruding from the back of the wall portion 64; structure protruding from the ends 18, 20; or structure protruding upward from the ledge). The seated or stop position could also be defined by interaction of the bottom end of the arm 110 with the back surface of wall portion 64 when a flex limit of the arm 110 is reached.
